a If the LSP Ping passes, you have completed the workflow for troubleshooting
services. Contact your Alcatel technical support representative if the problem
persists. See section 1.4 for more information.
b If the LSP Ping fails, verify the administrative and operational status of the
underlying L2 equipment.
Implement and verify the solution for the service problem.
•
If the problem no longer exists on the service, you have completed the
troubleshooting workflow for services. Disable the OAM diagnostics to
conserve system resources. See the 5620 SAM User Guide.
•
If the service problem persists, another type of problem may exist on your
service. Go to section 4.2 and repeat the troubleshooting workflow. If the
troubleshooting workflow does not identify the problem with your service,
contact your Alcatel technical support representative. See section 1.4 for
more information.
Enable the OAM diagnostics for the service. See the 5620 SAM User Guide.
Open the LSP Trace configuration form and clear the results from the previous
diagnostic session, if any.
Note — You must use the LSP Trace diagnostic to test the service in
both directions for the connection.
Configure the parameters for the diagnostic session and run the diagnostic. Figure
4-17 shows the diagnostic configuration associated with a LSP Trace from site ID
10.1.200.51/32 to site ID 10.1.200.52/32 using the network in Figure 4-1.
